Area health departments report steep increase in COVID-19 cases in 15-19 year olds in South Lyon, Fenton areas

The Livingston County Health Department, Oakland County Health Division, and Genesee County Health Department report a steep increase in COVID-19 cases in the South Lyon and Fenton areas since mid-July among individuals 15 – 19 years-old. Some of the cases reported attending large indoor and outdoor gatherings, including graduation parties and prom like events, during July.

“When attending both indoor and outdoor gatherings, it is important to stay 6 feet from others and wear a mask,” Dianne McCormick, Health Officer, Livingston County health Department said. “Socializing responsibly could help quickly turn things around.”

Preliminary information indicates a significant increase in cases among high school age students and those numbers could change as case investigation continues in the three counties.

In Oakland County, COVID-19 cases among 15 – 19-year-olds in the South Lyon area increased from three cases during late-June to mid-July to 42 from mid-July to early August. Similar trends for this age group have been observed countywide in Livingston and Genesee counties. For Livingston County, cases increased from three cases during late-June to mid-July to 19 from mid-July to early August, and in Genesee County, cases increased from 19 during late-June to mid-July to 94 from mid-July to early August.

The three health departments are conducting case investigations to identify individuals who have potentially been exposed. Initial information has determined that 15 – 19-year-olds from Oakland Livingston and Genesee attended at least six large gatherings.

If you attended a large gathering in the South Lyon and/or Fenton area during mid to late July and you think you are developing any of the symptoms of COVID-19 described below, call your physician or local health department.
